摘要:
A photographic element is disclosed comprised of a support and, coated on the support, at least one radiation-sensitive layer. The radiation-sensitive layer contains silver halide grains including a spectral sensitizer adsorbed on the surface thereof and, intimately admixed therewith, silver halide grains free of surface spectral sensitization and having a particle size in the range of 0.15 to 0.8 micron in diameter. The photographic element exhibits improved speed without a concurrent increase in graininess.
摘要(中):
公开了一种照相元件,其包括支撑体,并且涂覆在载体上至少一个辐射敏感层。 辐射敏感层含有卤化银颗粒,其包括吸附在其表面上的光谱增感剂,并与其紧密混合,不含表面光谱增感的卤化银颗粒,其粒径在0.15至0.8微米的范围内。 照相材料表现出改善的速度,而不会同时增加颗粒度。
